使用Intel® Parallel Studio优化程序性能实例分析

摘要(Abstract):
       Media SDK是一个软件开发库,包含解码、视频处理和编码三大模块。利用Intel®平台的硬件加速能力, Media SDK为低端用户提供了优秀的高清视频质量,极大的降低了播放高清视频的硬件门槛。此外,强大的视频APIs也减轻了程序开发者的工作负担,使他们能够集中精力去处理程序的逻辑模块,而不必关心于Media SDK内部的复杂编解码逻辑及其如何提高效率。本篇文章将着重讲述如何利用Media SDK提高程序的效率,面对的读者主要是视音频程序开发人员。

  • When test suites fail us (when they meet parallelism)

    Another week and another customer shared how messed up their test suites were because of parallel programming. So where are we going wrong?

    First, it is natural to feel confused and disoriented when a failure "escapes" into the wild.  In other words, when a bug is not caught by our test suites it is natural to DEMAND an plan to correct this failure!

    Second, it is common to fall back on a simple belief: an "escape" means we need MORE tests.

    This is where parallelism trips us up.
